Title: Transverse beam for rear vehicle axle - has reinforced section comprising U-shaped piece whose web rests the beam web
Inventor: ACKEL SABET
IPC: B60G21/055
Filed: 1974-04-20
Abstract: The web of the reinforcement is bent upwards at its ends. The limbs of the reinforcement taper off towards their ends so that the transverse beam forms a beam of uniform rigidity. Centrally the webs have a cutout which conforms with a stamping on the mounting plate of the rubber support so that the support can be centred using the cutout and the stamping. This rubber support is used to mount the rear axle transmission on the transverse beam. The transverse beam is formed as a U-shape, with the open ends extending forward from a chassis mounting to the wheel spring linkages.

Title: Pinning on brush for stretching belts on textile machines - has spines with cranked pressing surfaces uniformly spaced
IPC: D06C3/02
Filed: 1975-09-04
Abstract: A pinning-on brush has the form of a wheel on the circumference of which a number of spines extend radially to engage with an endless run of pins on a belt, so as to press a fabric piece fed between, on to the pins on the belt. The spines have at their radial extremities, a pressing section, cranked over so as to lie parallel to the axis of the brush. This pressing section may have an end piece turned back in the direction of the wheel, and this may be further reinforced by having the spine in the form of a "U" with two radially extending spines jointed by the pressing section at right angles to them, and parallel to the brush shaft. Does not wear quickly like conventional brush material, such as bristle, with the constant need for adjustment and frequent replacement.

Title: Illumination device for spirit level - uses light sources placed radially inside each level indicator and mercury switch for appropriate selection
Inventor: JOBST ALFRED
IPC: G01C9/32
Filed: 1975-09-06

Title: Rotary engine with piston reciprocating in rotor - has crank supported on shaft to reduce piston wall opening
Inventor: LAMM AUGUST UNO DR ING
IPC: F01B13/02
Filed: 1975-09-22
Abstract: The engine has a circular rotor (20) revolving in a casing (21). A double acting piston reciprocates in a diametral slot (22) running through the rotor. A crankshaft (25) runs through the casing and carries a crank (24) within the piston. The piston is supported on this crank. The crank is supported by a pair of crank arms (25, 25') which are connected to shaft sections (26, 26') which are themselves eccentric from the main shaft axis by an amount equal to the cam offset. It is only these eccentric sections which pass through the piston walls. The geometry is such that the relative movement between these sections and the piston is a straight line so that the openings (27, 27') in the piston walls can be straight narrow slots.

Title: Vehicle collision data recording system - uses electrolytic elements to store velocity:time characteristic data during collision period
Inventor: FICHTER MANFRED
IPC: G07C5/08
Filed: 1975-09-26
Abstract: Electrolytic storage elements are used as memory data devices for the recording of the velocity characteristic of a vehicle during a collision. Current applied in one direction to the electrolytic devices results in a silver deposition on a gold electrode at a known rate. Polarity reversal results in the process being reversed to obtain read out. The vehicle is equipped with a pulsed velocity generator a pulse generator coupled to the braking system and a pulse generating device indicating a shock condition, such as occurs during a collision. During accident conduction initial braking is followed by a sudden retardation at input followed by a linear retardation to rest. The relavent time periods and velocities are recorded in electrolytic elements, controlled by timer elements and transistor gating stages.

Title: Centrally controlled telephone exchange - has combined coupling panel divided in several working fields with own control units
Inventor: WEHREND KLAUS
IPC: H04Q3/54
Filed: 1975-10-01
Abstract: The working fields (LB1) have their own switching means. Parts of a connection to be built-up through separate parts of the switching panel are established by the separate switching means. Central control common for working field units works out various switching information for switching means of different working fields, and transmits them, possibly together with waiting signals, to the working field control units. They are stored in these units and/or in corresponding switching panel switching means. Then start signals are delivered from the central control in correct sequence to corresponding working fields which carry out the stored switching information.
